The Castle Guards are the veteran guards that protect Hyrule Castle. Many of them get tired on the job and would prefer if Link wouldn't bug them. The Castle Guards also tend to have a poor memory.  Early on in the game, the Castle Guards a bit wary of Link, making sure he doesn't do anything to harm Princess Zelda or wander around Hyrule Castle. The Castle Guards do have a high regard to authority and they speak with am much more pleasant attitude when Chancellor Cole is around. Eventually when the Chancellor appears, he will allow Link to pass the guards to attend the ceremony. Despite the fact that the guards speak nicely to Chancellor Cole, the Chancellor does not return that attitude, looking down upon them.. When the Chancellor is not around, the Guards don't speak nicely about him and they claim that Princess Zelda is just way to nice to him.
After Link has acquired the Recruit Uniform, the Castle Guards will still give him somewhat of a hard time, belittling him as he is just a Recruit. When Link is sneaking Zelda out of Hyrule Castle, the Castle Guards will be annoyed by Link's appearance, telling him to run off, as well as getting annoyed when Link is just staring at them. Some of the guards are a bit more intelligent and won't be distracted simply if Link talks to them. Instead, these guards are attracted to noise and Link can steer them away by tossing a rock at a nearby wall to make a sound.
After Link and Alfonzo are knocked out cold by Byrne, the Castle Guards will help bring them back to Hyrule Castle. Despite bringing them back, the guards don't believe Link that when he says that the Chancellor is a monster. When Link walks around the Castle, the guards are unsure what to do regarding the disappearance of the Spirit Tracks.
When Link acquires the Spirit Flute, he wants to leave through the back exit of the castle. However, a Castle Guard blocks Link's path, warning him of the beasts that are ahead. He informs Link that he should at least acquire a sword.
- ↑ "YAAAAAWN! I'm sleeeepy... I've been standing here since dawn... Hey, why don't you stop bugging me and get moving!" — Castle Guard, Spirit Tracks.
- ↑ "What is it, kid? We're kind of busy protecting Hyrule Castle right now. If you've got no business here, I'd suggest you scram! What's that? You're here for the engineer graduation ceremony? [.]Yes, sir![.]No, sir!" — Castle Guard, Spirit Tracks.
- ↑ "What?! Then why are you talking to me? Can't you see I'm busy? Go on, get lost!" — Castle Guard, Spirit Tracks.
- ↑ "Ah, I'd completely forgotten that today was the graduation ceremony. Huh, I didn't know they gave engineer certificates to little kids like you... I guess times are a-changing. Well, go on in." — Castle Guard, Spirit Tracks.
- ↑ "HALT, RECRUIT! You're training! Where do you think you're going? I don't tolerate deserters!" — Castle Guard, Spirit Tracks.
- ↑ "Go up the central stairs to the throne room. That's where Princess Zelda is. And don't you go wandering around the castle!" — Castle Guard, Spirit Tracks.
- ↑ "Hey, what are you up to? If you're not supposed to be here, quit skulking! Eh? Graduation ceremony? I guess I heard something about that. Well, it's up in the throne room. The stairs will take you there." — Castle Guard, Spirit Tracks.
- ↑ "The princess's throne room is up these stairs. Only invited guests are allowed in. What that means for you is...GET LOST!" — Castle Guard, Spirit Tracks.
- ↑ "What's all the commotion here? Oh, good day, Chancellor Cole! Apologies for the disturbance. This boy says he's come to see the princess! Is that so? You're here for the graduation ceremony? But you're so young. What a waste of resources. The Spirit Tracks are vanishing, yet the princess insists on performing these ridiculous ceremonies. Well, come along, boy. We must get you to your ceremony! Follow me!" — Chancellor Cole, Spirit Tracks.
- ↑ "Don't just stand there drooling, Private! Move aside!" — Chancellor Cole, Spirit Tracks.
- ↑ "He's so full of himself! Princess Zelda is so nice, she lets the chancellor get away with anything! Now he struts around the castle as if he were king!" — Castle Guard, Spirit Tracks.
- ↑ "Just a recruit, but already on special patrol duty? You must be good! We have to make sure that there are no unwanted guests hanging around." — Castle Guard, Spirit Tracks.
- ↑ "Recruit, you should be patrolling outside! Only elite guards have what it takes to guard areas near the princess!" — Castle Guard, Spirit Tracks.
- ↑ "Don't you have work to do, rookie? Why don't you go cut the grass or something?" — Castle Guard, Spirit Tracks.
- ↑ "What's that look for? Is something in my teeth? Why are you skulking around me? It's creepy! Scram! You're interfering with my duties!" — Castle Guard, Spirit Tracks.
- ↑ "The first rule of patrol duty is vigilance, even when people are talking to you. Furthermore, if you hear any suspicious sounds, investigate them at once. Only once you can do these things on instinct will you be a true watchman!" — Castle Guard, Spirit Tracks.
- ↑ "...I really have no idea what you're talking about, little guy! And I certainly don't know anything about the princess being kidnapped. Or, for that matter, the chancellor being a monster! That's just crazy talk!" — Castle Guard, Spirit Tracks.
- ↑ "We're all waiting to see what's going on with the disappearing Spirit Tracks! And do you know where the princess and the chancellor are? We could really use their help right now!" — Castle Guard, Spirit Tracks.
- ↑ "What is it, Recruit? Eh? You want to leave through this door? Well, I can tell just by looking at you that you aren't adequately prepared. There are all sorts of strange beasts on the other side of this door. It's not the kind of place you want to go without a sword!" — Castle Guard, Spirit Tracks.
